As we have never done a signature campaign before we looked at the LIR thread and used it as a guide. Relax, there is no scam involved at all. We are currently
having our own designs created.
If you have never done a signature campaign why you don't hire a campaign manager , also you can make a signature design contest to get new and unique signature for your campaign , it is better than copying others signatures , I see you have good payment rates , so you have enough balance to buy a signature design and hire a manager or escrow.
He is done with signature he have his own original design now and the really question here now is how he can handle this campaign if he dont have experience on running any similar of it? And some suggestion is good but i think he can do it at here own and he only needs to do is observe the other campaigns flow and sort those participants who wish to join to his campaign,
